Subject: bpo-38631: Avoid Py_FatalError() in _memory_release() (GH-18214)
X-Git-Tag: v3.9.0a4~203
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=47ee8a6063c22ec272fe7a2d95d12f7811ebb48b;p=thirdparty%2FPython%2Fcpython.git

bpo-38631: Avoid Py_FatalError() in _memory_release() (GH-18214)

If the export count is negative, _memory_release() now raises a
SystemError and returns -1, rather than calling Py_FatalError()
which aborts the process.
